Abstract
A binder (10) is for use in storing sheets (S) of paper having punched holes (H) in them. First and second end leafs (12, 14) respectively form outer covers of the binder. A center section (18) is intermediate the respective end leafs. One side of each of the end leafs is flexibly attached to opposite sides of the center plate for sheets of paper stored in the binder to be enclosed between the end leafs. A plurality of binder rings (22-30) hold the sheets of paper, and the rings are movable from a closed position to an open position so sheets of can be fitted into or removed from the binder. A backplate channel (48) is affixed to a centerplate (42), and one end of the rings fit through openings in this channel. The other end of the rings are secured to a ring channel (46) which, in turn, is secured to the center plate by screws (70). When the screws are removed, the ring channel can be lifted away from the center plate, opening the rings.
